But I'd have to say that Linus' entitlement is the uglier of the two. Albert is angry because he is not being given something that previous experience had taught him to expect as part of his pay; the fact that it is a large amount does not alter this situation. In effect, he worked for that money, so I can understand a feeling of entitlement to it. The fact that he does not see the wisdom in all employees temporarily foregoing this bonus to preserve the health of the company that provides such plum jobs is what makes him a dolt.
Linus is a bit harder candidate for sympathy in my view. You say that he "chose a different path" than Albert, making it sound like a value-neutral proposition, which it is; but by the same token, choosing one's path implies acceptance of the foreseeable consequences of that path. Because he "never really aspired" to the achievements of his brother, he could expect to hold jobs with both less compensation and less security. In an economic downturn, that is exactly the person who will have to accept a lower-paying job, since there will be more competitors in the hunt for that same job. It would be one thing if, by virtue of race, gender, or other characteristics, he had lacked the opportunity to advance further; the fact that he (presumably) had those opportunities, did not pursue them, but then refuses to grapple with the easily foreseeable consequences of that choice, makes me feel that his is the "worse" sense of entitlement.
